HAY ELEVATOR AND CARRIER.

i EITIQN erming part of Letters Patent No. 305,666, dated September 23,18841 Application filed November 2'?, 1883.

2'0 @ZZ wiz/om, t may concern:

Be it known that I, MAReUs W. CHAMBER- LAIN, a citizen of the UnitedStates, residing at Branchville, in the county of Sussex and State ofNew Jersey, have invented certain new and useful Improvements in HayElevators and Carriers, of which thevfollowingis a specification.

My invention has reference to devices for elevating and carrying hay;and the said invention consists lin the improvements and combinations ofparts hereinafter fully described, whereby the pulley-block to which theload is attached may be easily and readily elevated for engagement withthe suspending and carrying device, and the movements o1" said carryingdevice made the medium of actuating the locking mechanism to secure thesaid pulley-block to said carrier.

In the accompanying drawings, forming part of thi-s specification,Figure 1 illustrates in elevationa structure embodying my improvements,one side being removed to illustrate more clearly the arrangement ofparts; Fig. 2, a somewhat similar view, the parts being represented in adifferent position. Fig. 3 is a detail view showing the arrangementot'the carrier rail or way, and Fig. 4 is another detail view representing`one ot' the plates forming the sides ofthe carrier proper.

` The carrier proper consists, primarily, of two plates, A, Figs. 1, 2,and 4, which are arranged parallel with each other, and one or both ofwhich are provided with a series of lugs or projections, a b, whichmaintain the plates in Vproper relative position to provide anintermediate recess between them. The plates A are perforated at thepoints where the lugs c b are located for the vpassage of securing-boltsc. Each lower corner of each plate A is rounded, as shown most clearlyin Fig. et, and perforated to form a bearing for one end of a bolt, d,upon which is mounted and turns a grooved pulley, B,each plate A beingcutaway adjacent to the periphery of said pulley to form a curvedchannel, c, Fig. l. The lugs b are secured inan incline, to form betweenthem a space, which constitutes the approach to a rectangular recess,f,formed centrally between the plates. 'A slot, g, is .formed in theplates, so as to register with (No mode'.)

each other when the plates are secured t0- gether.

The securing or locking device consists of a plate, C, which iscentrally pierced by a bolt or pivot, h, the ends of which normally bearin the bottom of the slots g. This plate C is cut away or otherwiseformed at its lower portion to present two bolts, D E, which,when theplate C occupies its normal position, (illustrated in Fig. 1,)terminates flush with each side of the recess f, while the lowerportions of such terminals are notched toreceive the upper ends of thelugs b, thereby preventing oscillation of said plate on its bolt h whilein said position. Theupper portion of said plate C is eut away, asindicated in Figs. 1 and 2, on either side of which cut-away portion theplate is extended to form ears i. Two vertical curved arms, F, areformed integrally with the plates A, and are perforated at their ends toform bearings for the shaft j oi' a roller, G, which bears upon the railor way H to suspend the carrier. A strap, I, is securedto and dependsfrom the under side of the rail H.

J refers to the pulley-block, in which turns the pulley K, and from thelower portion ot' which depends the link k, designed for attaehment tothe load. The upper portion of said block is extended and tapers toconstitute a bail or loop, Z. The operating-rope M is passed around thepulleys B and K, as illustrated in Figs. 1 and 2, one end being knottedto provide for the connection of said rope with the carrier withoutinterfering with the capacity of said rope for sliding through one ofthe pulleys B to lower the pulley-block J. The load being attached tothe hook 7o, the free end of the rope is pulled, thereby elevating thepulley-block J and its attached load until the bail Z of the same entersthe space f, contacts with the plate C, and lifts it in its slottedbearings, the bolts D E becoming disengaged from the ends of the lugs b,oscillation of said plate C on its pivot being prevented by reason ofthe depending stop I entering the space formed by the cut-away portionof the plate C between the ears t'. Then the limit i of the rise of theplate O has been reached, further traction on the rope will cause one ofthe ears t' to bear` against the side of the stop I, and thereby tiltsaid plate, as indicated in IOO Fig. 2, causing one of the bolts,'1),ol'the saine to pass through the bail Z of the pulley-block and secure thesuspension of said block and its load.

With the parts in the position above described the carrier may be ymovedalong the rail, the earst' of the plate C'clearin g the stop. Anotherstop, similar to the stop I, is arranged on the rail at the limit of thecarriers travel, and is contacted with by one of the ears t' of theplate G to restore said plate to its first position and drop the load.

In Figs. 2 and 3 I have illustrated a constructionprovided ior theproper suspension of. the rail. A bar, m, is secured to the beams a ofthe roof, and has centrally pivoted thereto a yoke, o, the lower portionof which is perforated for the passage of the upper threaded end of arod, p, held in engagement with said yoke. Thelower end of said rodpierces the rail or way to receive a suitable nut to suspend the way. Bythis construction the rail is readily, easily,pand securely suspended,and capable of yielding to swing under the movements of the carrier toprevent ]'ar or strain encountered by rigid suspendingdevices.

I claiml. The combination, in a hay elevatingand carrying -device, of acarrier-frame, suspending-rollers connected therewith, an operatingropeconnected to the said carrier-frame and suitably guided, a pulley-blockhaving a loop and containing, a pulley around which said rope passes, abolt-plate adapted to be locked in a disengaged position and capable ofvertical movement to become disengaged and tiltedfto'pass through thepulley-block loop when the pulley-block is elevated,substan tiall y assetvforth.

2. The combination, in a hay elevating` and carrying device, of acarrier-frame, suspending-rollers connected therewith, an operatingropeconnected to the said carrier -frame and suitably guided, a pulley-blockhaving a loop and containing apulley around which said rope passes, abolt-plate adapted to' be locked in a disengaged position, and capableof vertical movement to become disengaged and tilted v'to pass throughthe pulley-block loop when the pulley-block is elevated, and a guiderail 'or way having a loop adapted to contact with said bolt-plate torelease said pulley-block, substantially as set forth. l

8. The combination, in a hay elevating and carrying device, of acarrier-frame, supporting-rollers connected therewith, an operatingropeconnected to the said carrier-frame and suitably guided, a-pulley-blockhaving a loop and containing a pulley around, which said rope passes, abolt-plate adapted to tilt to pass through the pulley-block loop whenthe pulley-block'is elevated, and` devices for locking said bolt-platein disengaged position, substantially as set forth.

4. The combination, in a hay elevating and carrying device, of abarrier-frame, supporting-rollers connected therewith, a plate pro-.vided with two bolts and adapted to tilt in either direction to throweither of said bolts alternately into play, substantially in the mannerand for the purpose set forth.

5. The combination, in a hay elevating and carrying device. of acarrier-frame, supporting-rollers connected therewith, a plate providedwith two bolts and adapted to tilt to throw either of said boltsalternately into play, and devices for locking said plate in a normalposition, substantially asset forth.

6, The combination, in a hay elevating and carrying device, of acarrier-frame, supporting-rollers connected therewith, a plate journaledand-adapted to play vertically in a slot and provided with a bolt,devices for locking said plate in a disengaged position. when bearinglin the lower portion of the slot and capable of releasing the said platewhen elevated in the slot, substantially as set forth.-

7. The combination, in a hay elevating and carrying device, of thepivoted yoke, withrod connected vertically adjustable thereto, andhaving secured at its lower end the guide rail or way, substantially asset forth.
